Problems solved by technology

At present, there are physical methods, chemical methods, biological treatment methods and other methods for sewage treatment. Although there are many types of treatment methods, the following problems generally exist in many treatment methods: high economic cost, complicated treatment process, and inability to treat harmful substances at one time , especially heavy metals that require multiple repeated treatments; due to incomplete sewage treatment, the treated water sources still cause varying degrees of harm to the human body

Embodiment 1

[0020] A kind of sewage treatment agent, the weight percentage of its raw material components is shown in Table 1.

[0021] In the above-mentioned sewage treatment agent, the raw material sulfate is aluminum sulfate, the alkalizing agent is sodium hydroxide, and the polymer flocculant is anionic polyacrylamide.

[0022] The method for preparing the above-mentioned sewage treatment agent is as follows: the magnesium oxide and the macromolecular flocculant in the raw materials shown in Table 1 are simultaneously added to the mixer for 10 minutes through the feeding machine; then, the remaining raw material zeolite is passed through the feeding machine. , sulfate and alkalinizing agent are added into the same mixer, and the stirring is continued for 10 minutes; then the products obtained by stirring are separately packaged through a blanking packaging machine.

[0023] In the preparation method of the above-mentioned sewage treatment agent, magnesia, zeolite, sulfate, alkalizing ...

Embodiment 2

Abstract

The invention relates to a sewage treatment agent as well as a preparation method and application thereof. The sewage treatment agent is composed of magnesium oxide, zeolite, sulfate, an alkalizer and a high polymer coagulant. The sewage treatment agent disclosed by the invention, when used for treating sewage, can physically adsorb pollutants in water, in particular ultra-micro molecules, other components can perform differentiated treatment on other pollutants in the water and especially acid pollutants can be decomposed and converted completely, and by processing suspended materials through flocculation of sulfate and the like, harmful substances are cladded and such heavy metals as chromium are agglutinated under attractive and repulsive force between ultra-micro particles, so that the harmful substances are prevented from being dissolved; moreover, the sewage processing agent is large in flocculant granules, short in settling time and relatively low in sludge, and therefore thorough sewage treatment is realized; treatment rate can reach more than 95%; regenerated water source after treatment is free from harm, and the processed water not only can reach discharge standard but also bring about benefit for recycling; and the sewage processing agent is suitable for popularization and application in the fields related to domestic and industrial wastewater comprehensive treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent, a preparation method and an application thereof. Background technique [0002] With the continuous development of industry, the use of water resources also increases, and there is less than 1% of fresh water on the earth and only about 0.007% of it can be directly used by human beings. Therefore, saving and reusing water resources Resources become the focus of attention. In the reuse of water resources, sewage treatment is the top priority. At present, the methods of sewage treatment include physical method, chemical method, biological treatment method, etc. Although there are many kinds of treatment methods, the following problems are common in many treatment methods: high economic cost, complicated treatment process, and inability to treat harmful substances at one time , In particular, heavy metals require multiple repeated treatments; the ...
